IMPROVEMENT N MILK-GANAS.V

Specification forming part of Letters Patent No. 154,910, dated September 8, 1874; application led AugustlQ, 1874.

To all whom t'mcy concern:

Be'it known that I, HENRY H. ROE, of Madison, Lake county, Ohio, have invented certain new and useful Improvements in Milk- Gans, of which the following is a specification:

This invention is directed particularly to the construction of the bottom of the can.

It has been my object to obtain the requisite support and protection for the lower part ofthe can-body; the necessary supportand protection for the bottom proper of the can; a convenient means of taking hold of and handling the can; a strong, cheap, and durable bond of union between the can body and bottom-in other Words, to assemble in one device all the various advantages which are found distributed among the most approved can-bottoms now in use, but which are not found so assembled in any one can-bottom heretofore made, so far as I am informed.

The manner in which I obtain this result can best be explained and understood by reference to the accompanying drawings, in which- V Figure lis a vertical central section of a canbottom made in accordance with my invention. Figs. 2 and 3 are like sections of modified forms, embodying the same general principle.

A is a tinned wrought-iron hoop, formed with an internal annular shoulder, a, and with an internal groove, b, just `above the shoulder. B is a concavorconvex disk of tinned`wroughtiron, fitting in the groove b, and resting on the shoulder a.. The hoop and the concave-convex disk together constitute the can-bottom.

The hoop is made from wrought-iron, which, first rolled to the proper section, is cut to the requisite length, and, after having rivet-holes punched in its ends, is bent into the form of a round hoop. To the abutting ends of the hoop is applied a clip or plate with rivet-holes to correspond with those in the ends of the hoop, and thertwo are riveted together and then properly tinned. The concavo-convex disk B, with its edge slightly turned down, is then inserted from the top of the hoop, and its edge is then thrown out into the groove b by proper tools. In this way the disk is held iirmly in its place, and requires no adjustment when the bottom is to be applied to the body of the can. The entire bottom is also thereby stiffened and held in shape, and the shoulder at a is stronger, inasmuch as it extends into the body of the hoop. For these reasons I prefer to form the hoop with groove bin conjunction with the shoulder a; but, if desired, this shoulder may be dispensed with, in which case the bottom will be as represented in Fig. 2.

In lieu of having the disk rest fiat on the shoulder, as indicated in Figs. l and 2, it may have its edge turned down, forming a downwardly-projecting ange, which rests on the shoulder a, as in Fig. 3.

The body of the can is indicated in the several figures by the dotted lines C. It is made,

.as usual, to iit closely within the hoop A, with its bottoni part resting on the disk B, and is soldered to the hoop or bottom on the inside at c, and on the outside at d. The body of the can may also be riveted to the hoop, but I consider this unnecessary.

The lower edge of the body may be left straight, as in Figs. l and 3, or it may be turned in, as in Fig. 2.

When the bottom is made as above described, it will be noted that the disk will be as stiff and permanent as though it were in one piece with the hoop. It combines in one all the advantages of a disk with an upturned annular han ge and a disk with a downwardly-turned annular flan ge. rlhe bottom is quite as strong as, and indeed even stronger than, either of the bottoms last referred to, since the hoop, being separate from the disk, can be made of much heavier and thicker metal than would otherwise be practicable. The joint between the bottom/and body is perfectly protected and concealed by the hoop, which also is the main connecting medium between the body and the disk. The cost of manufacture is not greater, and, indeed, is even less, than that incurred in making the better kinds of can-bottoms now in use.

The disk B may have either its convex face or its concave face uppermost. I prefer, of

course, the former. I have described the bottom with special reference to its use in a milkcan, but it will of course be understood that the can to which it is applied can be used for any other purpose desired.

Having now described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The can-bottom consisting of the internally-shouldered hoop and concavdconvex disk, constructed and fitted together as herein set forth.

2. The combination of the hoop having an annular internal shoulder, and a groove just above the shoulder, with the conoavo-convex` disk resting on' said shoulder, with its edge fitting in said groove, as shown and described.

In testimony WhereofIhaVe hereunto signed my name this 17th day of August, A. D. 1874.

HENRY ILROE.
